Hazy day at T1

Things are quite busy here at T1 and we are all anxiously awaiting the delivery of the 3 NCAR seacontainers. The past few days have been quite polluted as you can see from this photo from the roof of a UTTEC classroom building. I have four instruments on the roof, including this cloud camera. This instrument takes a photo of the sky every minute and I use these images to calculate the percent cloud cover. During the first week of MILAGRO it has been very dry and we have had essentially cloud-free skies the whole time. I am interested in looking at how clouds and aerosols impact surface level ozone production, so I need to know if the changes in sunlight are from the thick aerosol haze or from clouds. So far the changes have all been from the haze.
P.S. Please feel free to email me at: blefer@uh.edu if you have any questions.
